Videos you paid for. In that case, this might be relevant. Might. It might work, it
might not. You have to try it to see.
Assuming you figured out from our "too fast" discussion how to locate the HLS master
manifest, then you must use the URL of the HLS master manifest in your invocation of
ffmpeg like this:
https://userid:password@the rest of the URL as you already captured it
If your ID is your E-mail address, then you have to use a little trick like this:
https://ag%40gmail.com:password@the rest of the URL as you already captured it
I'm making up that E-mail address for the purposes of explaining things here. You must
replace all @ signs with %40. That's because the @ sign separates the login information
from the URL. You would confuse things by coding @ in your user ID. Similarly, if your
password contains any @ signs, replace those with %40 as well.
Let's hear from you whether that helps any.
